WILHELM STABY, OF LUDWIGSHAFEN-ON-THE-RHNE, GERMANY.

RADIATOR-VALVE.

To all whom t may concern.'

Be it known that l, VViLi-IELM STABY, head governmental counselor, of Ludwigshafenon-the-Rhine, Germany, have invented new and useful Improvements in Radiator- Valves, of which the following is a specification.

The present invention relates to improvements in radiator valves especially adapted for use with radiators upon railroad cars, and.refers more particularly to novel and improved arrangements for feeding t-he steam to the various radiators upon a train and the regulation of the heat in such radiators. With this object in view a double connection of the radiators with the main steam pipe is provided in which double acting valves are arranged in such a manner that through one of these connections the steam enters the radiator while through the other the air and products of condensation are carried oft.

In the accompanying drawings: Figure 1 shows a. radiator with the valves according to the present invention in section. Fig. 2 is a vertical section through the valve arrangement on an enlarged scale. Fig. 3 is a section on line 3-3 of Fig. 2. Fig. 4 is a section on line 44 of Fig. 2.

Each of the steam radiators 1 arranged atA convenient places upon a railway car, kas

shown in Fig. 1 by way of example in form of a cylindrical hollow body, is connected with the main steam pipe 2 usually arranged underneath the floor of the car, by two pipes 3 and 4 embedded in a common valve casing 5. One of the two connecting pipes, 3, is preferably arranged to connect with the upper part of the radiator; it is wider than the other pipe, 4, and is used for feeding the steam, while the narrower pipe 4 in connection with the lower part of the radiator, is used for carrying off the water of condensation and the air from the radiator.

The common valve casing 5 of the two pipes 3 and 4 forms an essential part or" the invention, and contains two ducts 6 and 7, the wider of which is formed with a flanged part 8 to which is secured the steam inlet pipe 3 by means of a connecting flanged sleeve 9 and an interposed suitably beveled packing ring 10, said parts being held in place by conveniently arranged screws.

At the lower end of the valve casing an aperture 11 is provided surrounded bythe conical face of a joint 12. By means of a Speccation of Letters Patent.

suitable flange 13 as shown in Fig. 5, of a pipe hanger 14 and of two bolts 15, the valve casing is fastened in the well known manner' over an opening in the steam heating tube 2 and a brass or bronze packing ring 1G insures a tight fitting connection. Laterally disposed to the part 8 of the valve casing 5 is the. drain pipe 4 of the radiator which is in turn connected to said casing 5 by means of the flanged sleeve 40 and the interposed beveled packing ring 41 and two bolts serve to secure tlie parts in position. From the point of connection of pipAe 4 with said casing 5 a duct 17 is extended through said valve casing 5 and extends at the bottom, within the steam inlet duct 6, in an eX- tension 19 of the connecting medium 5 which protrudes as far as to the center of the main steam pipe 2. rEhe steainpassing the mouth of said extension 19 through the main pipe 2 produces a sucking action at the discharge end of the duct 17 so that the products of condensation collect-ing in the pipe 4 and the lower part of the radiator `1and the air present in the radiator are drawn ott. Consequently steam is forced into the radiator through the duct, 6 andthe pipe 3 so as to insure a safe and uniforinheating effect.

In order to allow a regulation of the heating effect of the several radiators, preferably in the common pipe valve casing 5, a double acting valve is provided for the two pipes as shown in Figs. 4 to 6. 1Within the steam inlet duct 6 a cylindrical valve chest 20 is provided horizontally disposed in the valve casing 5. At one side this chest is closed by means of a threaded nipple 21 having in its center a cylindrical bore 22 for the reception of one end of a spindle 23. This spindle 23 extends through the chamber 20 and carries at its opposite end a conically shaped valve member 24 itting into a correspondingly formed recess in the valve casing Beyond the conical valve member the spindle carries a square shank 25 on which a controlling lever 26 is held in position by means of two nuts 27 secured upon the end of the spindle, said lever serving to turn the spindle. Within the bore 22 of the nipple 21 a spring 28 is arranged which under mediation of a bearing cap 29 presses against the extremity of the spindle 23, thus forcing its conical valve member 24 into the correspondingly shaped recess of the casing 5. `Within the chamber 2O of said medium a turning slide valve 30 is provided which with its cylindrical periphery bears closely against the upper part of the cylindrical inner surface of this chamber at the point where an extension 60 of the steam inlet duct 6, leading toward the pipe 3, eXtends into this chamber 20. Y

As will be understood from Fig. 5 the turning slide valve is comparatively narrow in the direction ot rotation andis kept in position by two lateral arms 31 of the spindle 23 or is respectively carried along during the rotation, while an adjusting pivot 23, elevated by a spring 32 and located in a cross boring of this spindle forces the turning slide valve into contact with the cylindrical inner surface of the chamber 20. A straight duct 17 passes through the valve casing 5 and in the plane of this duct 17 a groove 34: is provided extending over about three-quarters o'l' the periphery of this valve member; as will be seen from Fig. 6: this is done in such a way that in the central position in which the slide 30 is closed, as shown in Fig. 5, the entrance opening of the lower part of the duct 17 traversing the extension 19 is closed. Then the upper part of the duct 17 is connected by means of the groove 34 and of a radial boring 35 in the medium 5 with a tube 36 leading to thev atmosphere. ln the position as represented the turning slide 30 is shutting olf the steam inlet duct 6 of the radiator. Simultaneously therewith the drain pipe 17 is also shut off by the valve member 241. The interior of' the radiator is connected with the ambient air by the tube 4, the upper part of the duct 17, the groove 341, the duct 35 and the tube Copies of this patent may be obtained forve cents each, by addressing the Commissioner of Patents, l

36 so that the water of condensation collected can flow out allowing the air to ent-er into the radiator. By means of the lever 26 the spindle 23 is turned suiiiciently to allow the slide 30 to clear the corresponding opening. Simultaneously therewith the duct- 17 is shut oil' by the conical valve member against tube 36 and a connection between the upper and the lower part of the duct 17 is then established by the groove 34. Now the steam can enter `from the duct 6 to the tubes 3 into the radiator while owing to the suction power of the steam passing the extension 19 'the air in the radiator 1 is drawn oii through the drain pipe 4, the duct 17 and the groove 34. By partially opening and closing the slide 30 the desired regulation of the steam to be fed to the radiator can be effected.

I claim:

The combination Aof a main steam pipe, a radiator, a steam connection leading from said main steam pipe to said radiator, a water connection lead-ing from said radiator to said steam pipe, a connection leading from said water connection to the atmosphere, and a unitary valve structure pro? vided with means for simultaneously closing said steam and water connections against said main steam pipe and opening said water connections to the atmosphere.

In testimony whereof I afiX my signature in presence of two witnesses.
